car: 98 stratus.

last owner put in a new compressor in april. I drove the car straight to boston (~ 6hrs) with the a/c on full blast. On the way back, the a/c wouldn't work. I'm going to be taking this to a mechanic at the end of the week, but I'm looking for a little car-talk-esque advice. A friend of mine said that older cars use freon which sometimes needs to be refilled (?). Should I be thinking happy thoughts or what?
 
If you're leaking freon, then there's a problem. In a properly working car, it should never need to be refilled.

Sounds like a system leak / no freon. that isn't the same as a new compressor.

is that the symptom of a freon leak rather than a compressor failure? IE: trip 1 works 100%, trip 2 works 0%, no graduate loss of cooling power-

He's saying that it HAS a new compressor.

There are quite a few things that could be wrong... Anything from a bad pressure switch to low on freon. If it is low (which is the most likely cause), then you have a leak somewhere. If this is indeed the case, may want to see if the leak should've been caught during the initial repair, and see if there's a warranty issue.

If you do need to pay for the repair (say... evac/recharge, 2lbs freon, and repair the leak), the chances of you getting out out of the shop for less than $200-$250 are slim.

Yes, because there is a low pressure switch in the system. If the system pressure gets too low, it will turn off the compressor.

OH i see. It HAS a new compressor, not that he thinks he is going to NEED a new compressor even though it was just replaced. Interpreted his topic wrong.
 

It all depend on what your car had for AC...the old freeon or the newer "environment friendly" stuffs.

I had the same problem with my AC becauce I haven't turn it on for serveral years (the seals cracked), and now the mechanic shop want to replace all seals & compressor and convert over to the newer AC for $1200.

If you have newer AC & only need seals replacement and a recharge, then it shouldn't cost you much more than a few hundred bux to do so.

And then there is also the illegal propane method.
 
A bad air compressor led me to trade in my last vehicle for a newer one. It was going to run me $1500, after I had already put in 2500 into the vehicle. Sometimes it's just best to cut your losses.

i think most people use "freon" when they mean to use a more general term like "coolant"

last question. when the compressor gets replaced, does the freon have to be recharged?

Absolutely, since the system is under pressure, you have to evacuate it first.

You mean "refrigerant". 😉

But yeah, technically it isn't "Freon" (r12). Since the early 90's, it's been replaced with r134a. The Stratus (since it debuted in 1995) has always used r134a.

What do they call r134a? Is that Puron?

No... Puron is a residential refrigerant and is an "environmentally friendly" replacement for r-22.

I'm not sure that r-134a has a brand name.

 
probably have a leak.

you can tell if your compressor is gone because it turning on the belt makes a whine

My wife has the same car. The compressor in it locked up and I replaced it a
couple of weeks ago. It was about $250 from autozone. Dealer price was
just over $500. Napa was just over what the dealer wanted. Checker was
almost $300.

I put in the compressor from Autozone, and once again, am kicking myself
for using Autozone crap. It started making noise two days after installation.

R12 = Freon
R134a = Refrigerant
